wireproto: implement capabilities for wire protocol v2

The capabilities mechanism for wire protocol version 2 represents a
clean break from version 1.

Instead of effectively exchanging a set of capabilities, we're
exchanging a rich data structure.

This data structure currently contains information about
every available command, including its accepted arguments. It also
contains information about supported compression formats.

Exposing information about supported commands will allow clients
to automatically generate bindings to the server. Clients will be
able to do things like detect when they are attempting to run a
command that isn't known to the server. Exposing the required
permissions to run a command can be used by clients to determine if
they have privileges to call a command before actually calling it.
We could potentially even have clients send credentials
preemptively without waiting for the server to deny the command
request. Lots of potential here.

The data returned by this command will likely evolve heavily. So we
shouldn't bikeshed the implementation just yet.

Now test that it works with trunk/tags layout, but no branches yet.

Initial svn import

  $ mkdir projB
  $ cd projB
  $ mkdir mytrunk
  $ mkdir tags
  $ cd ..

Update svn repository

  $ svn co "$SVNREPOURL/proj%20B/mytrunk" B | filter_svn_output
  Checked out revision 1.
  $ cd B
  $ echo hello > 'letter .txt'
  $ svn add 'letter .txt' | filter_svn_output

  $ svn ci -m hello | filter_svn_output

  $ svn-safe-append.py 'nice day today!' 'letter .txt'

  $ cd ..

Convert to hg once and also test localtimezone option

NOTE: This doesn't check all time zones -- it merely determines that
the configuration option is taking effect.

An arbitrary (U.S.) time zone is used here.  TZ=US/Hawaii is selected
since it does not use DST (unlike other U.S. time zones) and is always
a fixed difference from UTC.

Test converting empty heads (issue3347).
Also tests getting logs directly without debugsvnlog.

Test that a too-new repository format is properly rejected:
  $ mv svn-empty/format format
  $ echo 999 > svn-empty/format
It's important that this command explicitly specify svn, otherwise it
can have surprising side effects (like falling back to a perforce
depot that can be seen from the test environment and slurping from that.)
